I saw it twice, you need to see it: ANPLAGD by Mladen Kovačević

Vera, a private detective retired to the village where she grew up as shepherdess, and Pera, the know-it-all peasant of many esoteric skills, are the last remaining leaf-players – both in the autumns of their lives, still strongly blowing into leaves. Josip is an amateur inventor set out to decode the obscure artistry of leaf-playing. “Unplugged” is an existential allegory about music played on tree leaves, humorously rattling between the most primitive of instruments and the most universal escapism of music. Music has rarely been so offbeat.
